Obama v. Clinton in the Senate

Elana Schor runs down a fairly comprehensive list of the significant differences between the candidates' voting records. It's hard to take away too much from this--these are a handful of votes out of many hundreds, etc, etc. But even looking through a constrained window such as this one, there does appear to be at least the beginnings of an unsurprising pattern: Obama has made generally wiser voting decisions on matters of foreign policy and Hillary Clinton has made generally wiser voting decisions on environmental issues.

My sense of it is that Obama has been somewhat reconstructed from his early, coal-driven, anti-environmental days, while Hillary Clinton remains a largely unreformed liberal hawk. But I suppose it'll be hard to say how true that is until at least one of them is off the campaign trail.
